Resumen:
The activity of complex heteropolytungstates of general formula α- [MII4(H2O)2(PW9O34)2]10- with M= Co(II), Zn(II), Mn(II) and Cu(II) (PWM) was investigated in the selective oxidation reaction of diphenylsulfide to diphenylsulfoxide in presence of tert-butylhydroperoxide as oxidant. The characterization of phases was performed by X Ray Powder Diffraction, XRD. All phases resulted isomorphous although PWCu is obtained as a mixture of two structural isomers [Cu2(H2O)2PW10O38]7-.
